此技能确保所有代码开发遵循TDD原则,并具备全面的测试覆盖率。
始终先编写测试,然后实现代码以使测试通过。
作为一个[角色],我希望能够[行动],以便[获得收益]
示例:
作为一个用户,我希望能够进行语义搜索市场,
这样即使没有精确的关键词,我也能找到相关的市场。
针对每个用户旅程,创建全面的测试用例:
describe('Semantic Search', () => {
it('returns relevant markets for query', async () => {
// Test implementation
})
it('handles empty query gracefully', async () => {
// Test edge case
})
it('falls back to substring search when Redis unavailable', async () => {
// Test fallback behavior
})
it('sorts results by similarity score', async () => {
// Test sorting logic
})
})
npm test
# Tests should fail - we haven't implemented yet
编写最少的代码以使测试通过:
// Implementation guided by tests
export async function searchMarkets(query: string) {
// Implementation here
}
npm test
# Tests should now pass
在保持测试通过的同时提高代码质量:
npm run test:coverage
# Verify 80%+ coverage achieved
import { render, screen, fireEvent } from '@testing-library/react'
import { Button } from './Button'
describe('Button Component', () => {

render(<Button onClick={handleClick}>Click</Button>)
fireEvent.click(screen.getByRole('button'))
expect(handleClick).toHaveBeenCalledTimes(1)
})
it('is disabled when disabled prop is true', () => {

expect(screen.getByRole('button')).toBeDisabled()
})
})

记住:测试不是可选的。它们是安全网,能够实现自信的重构、快速的开发和生产的可靠性。
development
Share durable, inspectable context and handoffs between Claude, Codex, Hermes, Cursor, OpenCode, and other agents through the local ECC Memory Vault. Use when an agent must save work state, transfer context, resume another agent's task, or search shared project knowledge.
development
Use when multiple consumers and providers must evolve an API or event schema without field drift, integration surprises, or one side silently redefining the interface.
tools
Query live GPU inventory, submit an authenticated Itô fixed-rate RFQ, inspect RFQ or procurement status, and run explicitly gated node qualification through the separately installed canonical CLI. Use when a user asks to find H100/H200 capacity, request a fixed compute rate, check Itô compute status, or validate GPU nodes.
data-ai
Instinct-based learning system that observes sessions via hooks, creates atomic instincts with confidence scoring, and evolves them into skills/commands/agents. v2.1 adds project-scoped instincts to prevent cross-project contamination.
